those holes mean that the reactors cannot and will not ever hold pressure. If they don’t hold pressure guess what else they don’t hold… They don’t hold water in (cooling) and they also don’t hold radiation from escaping. They need to still keep them cool because there is a molten mass at the bottom from everything that melted “corium”. Thats why the basements are full of super highly radioactive water, everything you pour in goes right back out. The more water they pour on em the more highly contaminated water there is to clean up… see where this is going? Eventually this IS going to highly contaminate the groundwater and seawater there. Who knows how far the effects are going to be felt.
Nuclear power is epic fail IMO.
